PAPER-BOX CONSTRUCTION.

Speccaton of Letters Patent.

Patented N ov. 22, 1921.

Application filed June 1, 1918. Serial No. 237,710.

To all whom t may concern.'

Be it known that I, HARRY BRIDGMAN SMITH, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Paper-Box Construction, of which the following is a specitication.

This invention relates to improvements in paper box construction employing ornamental edging strips.

Prior to the present invention, it has been the universal custom, in applying ornamented edging strips to covered box shells, to produce the edging strips as individual structures and then adhesively secure the strips to the box, these strips projecting into the cavity of the box from opposite side walls thereof. Certain inherent difficulties are present in the production of edging strips of this type and especially where. these strips vare of the embossed type, so that these strips have been practically limited in production as individual articlesl of manufacture, the general custom of the trade being to utilize the separate strip in producing the completed shell structure. Since the edging strips are manufactured separate from the covering blank, they necessarily carry an attaching portion in the form of a strip additional to the strip portion which projects into the box cavity.

I have discovered that it is possible to produce the ornamental portions of the edging` strip, even though this portion be of the embossed type, as extensions to the side wings of the shell covering blank, these portions being produced as an integral part of such blank, and at the same time overcome the inherent difculties which Vare present in the production of edging strip structures, among which is the effect of the embossing action on portions of a sheet with respect to the fiat remaining portions of the sheet.

A simple way to obtain this result is to produce the edging strip portions on a sheet or web of paper in advance 'of actually cutting the covering blank to its desired shape from the web, the edge-forming operation thus taking place in advance of the blankcutting operation so that the latter will be had on a sheet or web in which the effects of the edge production have been completed. The particular method which may be employed in the production of a combined blank and edging strips results in a great saving in the complete blank, as well as the finished box. The object of the invention is, therefore, the production of a covering blank having ornamented edging strips formed integral with the blank and-so positioned as a part of the blank as to permit the latter to be applied to the box shell in the usual manner, such application of the blank locating the strips at the proper point with respect to the shell, the strips overlying the marginal edges of the open box shell.

To these and other ends, therefore, the nature o f which will be readily understood as the invention is hereinafter disclosed, said invention consists in the improved construction and arrangement hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the accompanying drawings, in which similar reference characters indicate similar parts in each of the.views:-

Figure l is a perspective View showing, in full lines, a completed blank adapted for application to a box shell, and showing, in dotted lines, a way in which the same can be readily produced.

Fig. 2 is a perspective view, with parts broken away, showing the blank of Fig. l applied to the box shell.

Referring to Fig. l, the covering blank shown therein comprises a body portion a, side wings a', end wings c2, end laps as and side laps at. As shown,'each of the side wings a carries an extension o of substantially equal length with the length of the wing and of a desired width, each extension being formed integral with the wing from which it extends. Each extension is shown as of that type known in the trade as an embossed edging strip, the term embossed being used in its broader sense, including raised or cut-out gures, either or both combined, such as lace paper designs and the like. It is to be understood, however, that the invention contemplates otherwise ornainenting these extensions which form, when the blank is applied, facially ornamented extensions which constitute edging strips of the general type of ornamentation heretofore emp-loyed.

As shown in Fig. 2, Vthe blank is applied to the ordinary box blank to produce a covered box shell construction, the application of the covering blank serving to locate the extensions ZJ `in proper position to project into the cavity of the open shell extending over the side wing marginal edge portions of the open shell. Y

Obviously, a covering blank of this type is capable of being applied to the box blank with the simplicity of operation of the ordinary box blank, there being no requirement of a separate operation or a distinctstage for applying the edging strip or fly as has been the practice heretofore.

As heretofore pointed out, there are certain inherent diiculties in the production of edging strips which have been overcome by specific formations of the strips during the development of the art, this generally being by giving amargin of the strip a more or less embossed condition or by perforating l or otherwise forming the strip. The production of edging strips as an article of manufacture'has therefore been conned to the production of these strips as a separate formation adapted to be secured in position at the desired stage in the completion of the shell. i f

A simple method of preparing the blank isto pass a sheet between the dies which v form the ornamentalportions of the strip,

thus producing ornamented portions spaced apart the width of the bodyV portion and side wings of the blank. l The sheet is then passed to a blank-cutting die which cuts the sheet into the desired configuration, any excess length of the ornamented portions being discarded with the remaining waste.

The method can be practised efliciently and very rapidly by employing a web of paper of suitable width and length, this web being fed between rotary dies which operate to produce the ornamental effect in the direction of length ofthe web,the web then passing onward to a succeeding die structure which acts to cut outthe blank. This structure may be so arranged as to leave the end lap a3 of one blank attached to the similar lap of the succeeding blank, severing taking place at any desired point. In Fig. 1 I

have shown this general arrangement, the

space shown between an end of the blank shown in full lines and a dotted line blank representation, representing the waste material.

AS will .be understood, whether in sheet or web form,rno particular accuracy need be had las to the length of strip portion which the ornamenting dies may produce, the completed length being provided by the blank cutting die and therefore insuring absolute accuracy in the length and relative positions of the ends of the strips relative to `the side wings, at the same time preventing any possibility of canting or otherwise mispositioning the strip relative to the shell such as may take place in attempting to locate the individual edging strip of commercial practice on to the shell.

As will be understood, the particular form of the covering blank shown, is more or less illustrative, the particular wingend lap formation being that which may be employed in covering one type of box blank.

Obviously, the particular formation in this respect may vary to meet conditions where a different type of blank is prefered, the essential being that the edging strips should form the extensions for these outer edges of the wings of the covering blank which are to be applied to the box blank wings from which the strips are to extend.

While I have herein shown and described one form in which the invention may be embodied, and have pointed out simple ways in which the same may be produced, it will be understood that changes and modifications therein may be required or desired in meeting the exigencies of use, and I desire to be understood as reserving the right to make any and all such vchanges or modifications as may be found desirable or essential, in so far as the same may fall within the spirit and scope of the invention as expressed in the accompanying claims when broadly construed.

What I claim is z* 1. As a new article of manufacture, a covering blank adapted to be adhesively attached to the exterior walls of a paper box shell, said` blank being formed offlexible, readily foldable material, and comprising a body portion having integral side and end wings all of proper dimensions to cover the bottom side and end walls of the box shell, each of the side wing portions of theblank having integral facially embossed extenl sions constituting edging strips, said edging strips being relatively positioned to permit projection into the covered box shell in overlying relation to the marginal portions of opposite walls of the shell.
